Construct a right angled △PQR, in which ∠Q=90∘, hypotenuse PR=8 cm and QR=4.5 cm.
Steps of Construction:
i) Draw a line segment QR=4.5 cm
ii) At Q, draw a ray QX making an angle of 90∘
iii) With centre R and radius 8 cm, draw an arc which intersects QX at P.
iv) Join RP.
△PQR is the required triangle.
